Description
Bei in elektrischen Eisenbahnsicherungseinrichtungen benötigt man eine größere Anzahl von Leitungen, weil der Antrieb wahlweise in die eine oder andere Richtung bewegt werden muß und auch im Ruhezustand einen ÜUberwachungsstrom erfordert. In den meisten Fällen verwendet rnan,einen Motor mit zwei Feldwicklungen, wobei. jede Feldwicklung an eine besondere Leitung angeschlossen ist und nun je nach der gewünschten Drehrichtung die eine oder andere Wicklung Strorh erhält.When in electrical railway safety devices one needs a larger number of lines, because the drive can either be in one or the other Direction must be moved and requires a monitoring current even in the idle state. In most cases rnan used a motor with two field windings, where. each field winding is connected to a special line and now depending on the desired direction of rotation receives one or the other winding Strorh.
Gemäß der Erfindung kann man an Leitungen und Kontakten wesentlich sparen dadurch, daß man unter Zuhilfenahme von Sperrzellen die jeweils nicht benutzte Stelleitung als Rückleitung verwendet.According to the invention, lines and contacts can be significantly improved save by not using each of them with the help of blocking cells Control line used as return line.
Der Erfindungsgegenstand ist in_ den. Abbildungen beispielsweise erläutert.The subject of the invention is in_ the. Illustrations explained for example.
Fig. i zeigt ein Beispiel für eine Weichenschaltung mit .einem Hauptschlu.ßmotor, Fig.2 eine solche mit einem Nebenschlußmotor. Der Einfachheit halber ist die Steuerung der Ströme vom Stellwerk aus weggelassen: Sie kann in bekannter Weise über Stellhebel und Springschalter oder Batteriewechslermagnete oder durch Stellrelais und Spannungs@-,vechsler erfolgen.Fig. I shows an example of a switch circuit with .em Hauptschlu.ßmotor, 2 shows one with a shunt motor. The controls are for simplicity of the currents from the signal box omitted: You can in a known manner via levers and spring switch or battery changer magnets or through control relays and voltage @, changers take place.
Im Ruhezustand fließt der Überwachungsstrom, wie stark ausgezogen, über den überwachungsmagneten Ü io. :Der Überwachungsmagnet .wird abgeschaltet, z. B. durch einen Kontakt R i i des Stellrelais. Sobald Stellstrom eingeschaltet wird, fließt dieser nun in der eingezeichneten Pfeilrichtung P i und -gelangt über die Feldwicklung W i, die Ankerwicldung M i, Sperrzelle S i und Leitung L 2 zurück zur Stromquelle. Der Motor läuft um. Nach dem Umlaufen wechseln in bekannter Weise die Motorkontakte M2, M3, und es fließt nun ein Überwachüngsstrorn über Leitung L 2, Kontakt M 3 zum Überwachungsmagneten U io: Wird dagegen der Strom im, Stellwerk umgepolt, so fließt der Strom in der Richtung P:2 über Leitung L 2, Wicklung W 2,- Ankerwicklung M i, Sperrzelle S 2, Leitung L i zur Stromquelle zurück. Man benötigt also nur drei Leitungen L i, L 2, L 3 für Stellung und Überwachung.In the idle state, the monitoring current flows through the monitoring magnet Ü io, as if it had been pulled out. : The monitoring magnet .is switched off, e.g. B. through a contact R ii of the control relay. As soon as the actuating current is switched on, it now flows in the direction of the arrows P i and arrives via the field winding W i, the armature winding M i, blocking cell S i and line L 2 back to the current source. The engine rotates. After the rotation, the motor contacts M2, M3 change in a known manner, and a monitoring current now flows via line L 2, contact M 3 to the monitoring magnet U io: If, on the other hand, the polarity of the current in the interlocking is reversed, the current flows in the direction P: 2 via line L 2, winding W 2, armature winding M i, blocking cell S 2, line L i back to the power source. So you only need three lines L i, L 2, L 3 for position and monitoring.
In Fig. 2 würde beim Einschalten des Stellstrom.es in Richtung P i dieser einesteils über die Wicklung W i, Sperrzelle S i und anderenteils über die Ankerwicklung M i und über Leitung L:2 zurückfließen. Bei Stromrichtung P 2 dagegen fließt der eine Teil des Stromes über Wicklung W 2, Sperrzelle S:2 und Leitung L i zur Stromquelle zurück. Der andere Teil des Stromes fließt wieder von Leitung L:2 über die Ankerwicklung M i nach Leitung L i.In Fig. 2, when switching on the Stellstrom.es in direction P i this one part via the winding W i, blocking cell S i and the other part via the Armature winding M i and flow back via line L: 2. On the other hand, in the case of current direction P 2 One part of the current flows through winding W 2, blocking cell S: 2 and line L. i back to the power source. The other part of the current flows again from the line L: 2 via the armature winding M i to line L i.
Wie aus obigen Beispielen ersichtlich, ist man nicht nur in der Lage, mit drei Leitungen auszukommen, sondern erspart auch einen großen Teil der sonst notwendigen Motorkontakte.As can be seen from the above examples, one is not only able to get by with three lines, but also saves a large part of the otherwise necessary motor contacts.
Normalerweise braucht man bei einem Hauptschlußmotor vier Motorkontakte, während im vorliegenden Falle nur zwei 'benötigt werden.Normally you need four motor contacts with a main circuit motor, while in the present case only two 'are required.
